Permitted and Prohibited Items When Flying

Need to know the latest rules and regulations for carry-on items on flights in the U.S.? TSA (Transportation Security Administration) amended its rules for carry-on items, and this page has a wealth of information to help travelers prepare properly for their trips.
On Tuesday, September 26, 2006, TSA adjusted the ban on liquids, gels, and aerosols...
Air travelers may now carry liquids, gels and aerosols in their carry-on bag when going through security checkpoints.
With certain exceptions for prescription and over-the-counter medicines, baby formula and breast milk, and other essential liquids, gels, and aerosols, the following rules apply to all liquids, gels, and aerosols you want to carry through a security checkpoint.
1. All liquids, gels and aerosols must be in three-ounce or smaller containers. Larger containers that are half-full or toothpaste tubes rolled up are not allowed. Each container must be three ounces or smaller.
2. All liquids, gels and aerosols must be placed in a single, quart-size, zip-top, clear plastic bag. Gallon size bags or bags that are not zip-top such as fold-over sandwich bags are not allowed. Each traveler can use only one, quart-size, zip-top, clear plastic bag.
3. Each traveler must remove their quart-sized plastic, zip-top bag from their carry-on and place it in a bin or on the conveyor belt for X-ray screening. X-raying separately will allow TSA security officers to more easily examine the declared items.
